The peetha, tortoise-shaped, should be 25 feet long and wide. At peethaadi or starting end should be fixed the agni-kosha or fire place, the water vessel in the middle, and the smoke-container should be fixed at the other end.
The 3 koshaas are explained by Budila:
Ravi or copper, manchoulika, and tigma in equal parts should be mixed with kundodara metal, and be made into 3 inches thick pattika or flats. One pattika should be fixed on the peetha. In the fire place, kendra on the peetha a 4 feet long 6 feet high fire-place should be made. For stocking coal or wooden billets, a sort of walled table should be formed. Next a triangular fire-place should be formed, p. 105 with rods at the bottom for the ashes to fall down. In between the 2 parts the flat sheet should be fixed, fitted with keelakas or hinges for moving the peetha as desired. Three keelakas should be fixed at the fire place, one to fan the flames and straighten them, one to moderate or stimulate the flames, and one to distribute the flames evenly. A naala or pipe should be fixed on the fire kosa.
Another pipe with wiring, is to be fixed at the end of the fire-kosa pattika with a smoke transmitting pipe which will convey the smoke of the fire-place to the jalakosa or water container. From the fire kosa to the covering of the water kosa water pipes should be adjusted. In the water kosa enclosure the heat will rise to 5000 linkas in these tubes. The heated water will then give out hot smoke.
The size of the jalakosa or water container is 8 feet. Three triple-wheeled naalas or pipes should be fixed in the jalakosa: one to restrain the heated smoke from the water, one to amass the smoke, and one to lead the smoke into the dhoomakosa or smoke-container. The Dhoomakosa should be 6 feet wide and 4 feet high. In order to fill the kosha with smoke, necessary fittings should be provided. Above the jalakosa a dome-like covering should be erected. It should be provided with fittings, for folding up and opening out. To the front of the smoke container, two pattikaa wheels with holes should be fixed in order to let out the smoke or to restrain it. In order to operate the wheels two bhraamanee keelakaas or revolving switches should be provided. To the east of the Dhooma-kunda, 8 inches long window bars should be fixed with one inch spacings. Then in front of the yantra, in the middle, at top, at bottom, and on both sides, twin padmachakra keelakas should be fixed for spreading the smoke or restraining it. For storing the wood or coal a hole 11 feet wide should be arranged. The door covering it should be provided with needful fittings. To the north and south of the keelaka the heat-measure and speedometer should be fixed. Above them the timepiece. To the south, a telephonic device called ravaprasaarana or sound ringer, which will give alarm with 1212 sound wave speed, and which gives warnings for the plane's moving, halting, speeding, overspeeding, and danger imminence. An equipment with 5 holes giving 5 different sounds to indicate the above should be installed. On either side of the above, two 6 inches wide, 26 feet tall, Aaghaatha-naalas or pipes should be fixed. Between them two 5 inches thick metal rods are to be adjusted. At the foot, middle, and top of the naalas revolving p. 106 wheel keelakas should be fitted. By their revolving, the rods will strike each other. That will increase the speed of the plane. On the top of the naala pipes, air bellows with fittings should be fixed. Thereby the air force in the naalas will shoot up, and the speed of the vimaana will double.
Then on the four sides of the heated smoke kosha or container, shundaalas or elephant-trunk-like pipes should be fixed with wheeled keys as in vaatodgama yantra. By filling the shundaalas with the smoke and turning the keys as required, the movement of the vimaana in one direction or another, its gaining height and speeding out or halting, will be facilitated. Keys should be adjusted so as to make the shundaalas coil down like a water hose or keep erect. Two pipes made of 3rd division copper should he wound round the agnikosa, water kosa, and smoke kosa, or fire, water and smoke koshas, in order to absorb the excessive heat in them.
In order to part the wind in front of the vimaana, vaata-vibhajana chakra keela or wind-dividingwheel fittings should be fixed.
Having thus prepared the chaaturmukhoshmyaka yantra, or four-faced heating machine, it should be installed in the centre of the vimaana. By the air, smoke, and heat of the yantras below, the ascent and flight of the vimaana will be facilitated.
Regarding the speed of the vimaana, we have to consider the speed of smoke and other accessories mathematically, and conclude the possibility of the speed of the vimaana. The speed of the smoke from dhooma yantra is 2113 linkas. The speed of wind from the air blowing machine 2500 linkas. Wind from the naala-stambha blows at the speed of 600 linkas. This is the speed of the forces from the 3 machines on the peetha. Of the forces from the upper portion of the vimaana, from the chatur-mukhoshmyaka yantra, heat force of 3400 linkas emanates. By the four-faced heat yantra, and by operating the keys of the shundaalas, and the force of the wind, smoke and heat machines, the vimaana would be capable of a speed of 400 yojanas or 3600 miles.
This is Sundara Vimaana, and it has been described after consulting ancient works, and according to my humble capacity, says Maharshi Bharadwaaja.
This vimaana is of golden colour. Therefore it is called Rukma vimaana, Rukma meaning gold.
The Rukma should be made out of Raajaloha only. By duly processing, Raajaloha can be made to assume golden colour. That metal should be used for the vimaana.
"Yaana-Bindu" says, "After first producing golden colour for Raajaloha, the vimaana should be formed."
"Varna-sarvasva" mentions the colouring process:
Praana-kshaara or ammonium chloride 4 parts, wild Bengal gram 32 parts, shashakanda (or lodhra?) benzoin? 18 parts, naaga or lead 20 parts, sea-foam 16 parts, maakshika or iron pyrites 6 parts, panchaanana or iron 20 parts, paara or mercury 15 parts, kshaara-traya or 3 kinds of salt:
natron, salt-petre, borax, 28 parts, panchaanana or mica 20 parts, hamsa or silver 17 parts, garada or aconite 8 parts, and panchaamrita or 5 sweets--curds, milk, ghee, sugar, honey, these should be filled in the melter, and after boiling, and drawing the liquid through two outlets, fill in the crucible and place in furnace, and blow to 800 degrees' heat, and then transfer it to the cooler.
That will be Raajaloha, pure, golden-coloured, tensile, and mild. The vimaana, made out of this loha or alloy, will be very beautiful and delightful.
The peetha or ground plate of the Rukma vimaana should be tortoise-shaped, 1000 feet long, and 1 foot thick, or any other desired p. 108 size. On its eight sides, 20 feet long spaces should be fixed underneath the peetha. At each centre fixtures like birds' beaks should be attached with revolving keelakas. Then double iron-balls or wheels, in couples, should be fixed in each of the 8 centres.
Lalla gives the form of ayaschakra-pinda:
12 feet long and wide, and 8 kankushtas in weight, they should be made round like a grind-stone.
They should be inserted in the beaks at the 8 centres. From each chakra-pinda up to the electrical generator chain wires should be connected with switches.
One foot wide and 4 feet high poles should be fixed. They should have switches wired up to the electric pole. 8 inches wide wheels should be fixed in the middle of the pole, on either side, with wires. From the electric pole chain wires should enclose the wheels and be fixed in another pole with inside hinges. On the top of the poles should be fixed goblet shaped cups with buttonswitches like half-blooms with wheels and keys, so that on pressing the button with the thumb the wheels in the other pole will revolve from electric contact. Then the wheels in the electric pole will also revolve, producing 5000 linkas of speed.
Due to this electrical force, the ayah-pinda wheels beneath the peetha will beat against it and make it rise and move upwards. And by moving the switches of the wheeled poles above the peetha, the poles will revolve with speed, and accelerate the speed of the vimaana. By the concussion of the wheels underneath, and the action of the poles above, the vimaana will move upwards and gain height and fly with dignity.
Electric tube wheels aiding flight:
Above the peetha, naalas or tubes should be fixed at 1 foot intervals. On both sides of each naala toothed wheels 2 feet wide and 1 foot high should be fixed with proper keelakas. Taking electric wires through p. 109 the keelakas, and passing over the wheels and reaching the foot of each naala, they should be attached to wheels 3 feet wide and 3 feet high. In the midst of 20 naalas a pole should be fixed in the centre.
Preparing a pillar 4 feet wide and 4 feet high, and making a 2 feet opening in its middle, fix keelakas at the top, middle, and lower end of the opening. Two keelakas with 6 wheels, with glass coverings, with wires, and naala and leather covering should be fixed at the lower end for attracting electricity. In the middle part of the opening, for transmitting the current, a five-faced keelaka should be fixed, with 5 wheels, glass covering, 2 naala tubes, two wires, attached to 3 rods, and vessel containing veginee oil. By the flow of the current the wheels in the upper end should be made to whirl by properly adjusting keys. In front of the opening a big wheel should be fixed with gumbha keelakas. Similarly wheels should be fixed at the foot of each pillar. On top of them a four inch wide pattika or flat band should be adjusted commencing from the samsarga key chakra up to the front of the electric yantra. By operating that key, power will flow through the wires, and entering the key at the foot of the pillar set the wheels in motion. On the motion of the big wheel the sandhi-wheels in the naala-dandas will also revolve with speed, and the current will enter the 5 faced keelaka, and entering the oil vessel it will gather force, and passing through the 2 naalas, set all the wheels in the pillar in forceful motion, generating 25000 linkas speed, which will give the vimaana 105 krosa or nearly 250 miles speed per ghatika, or 24 minutes.
Having dealt with the mechanism for setting the vimaana in motion, we now consider the mechanism for giving direction to the vimaana in its course. In the 8 diks or directions of the peetha, pillars made of mica and shining like panchakantha, 2 feet thick and 15 feet high should be fixed at intervals of 10 feet. On the pillars should be built the passenger seating arrangements, and booths or locations for the machinery, as in the case of the Sundara Vimaana. The pillars should be made of mica only.
Its production is given in Kriyaasaara:
Shaara-graava or lime 25 parts, kshwinkaasatva or iron-sulphate 30 parts, gunja or wild-liquorice 28 parts, tankana or borax 12 parts, p. 110 roudree moola 8 parts, chaandree or kantakaari....solanum xanthocarpum flower salt 2 part, purified shoonya or mica 100 parts,, to be filled in koorma crucible, and heated in paadma furnace with blower to 800 degrees, and then poured into the cooler, will yield mica alloy most useful and attractive. Fashioning the pillars or walls or partitions and booths, and fixing the mechanisms for turning, circling, diving, and manoeuvring, in the fore and middle and aft of the vimaana, it could be moved in any direction as desired.
In order to make the vimaana change its course from one path to another or one direction to another, revolving keelakas should be fixed on the eight sides of the vimaana. Two keelakas should be made, purva and apara, or right side and left side. They should be fitted together.
By operating it, the vimaana could be made to change its course one way or another. In order to operate the keelaka, at the peetha moola, on the 4 sides crescent shaped naalaas or tubes, 2 feet wide and 2 feet high should be fixed. 4 inches long metal rods should be fixed inside the naalaas on either side. One foot wide and 1 foot high wheels should be fixed in them. They should be wired all around. Such crescent naalas should be fixed on the 4 sides of the peetha. In order to set the wheels in the naalas in motion big wheels should be fixed at the beginning, middle, and end of the naalas. By turning the top wheel with speed the wheels inside the naalas will revolve.
That will force the keela-shankus to twist round so as to force the vimaana to change its course in the required direction.
Having explained the vimaanas commencing from Shakuna to Simhikaa, Tripura vimaana will now be dealt with.
This vimaana has 3 enclosures, or aavaranas or tiers. Each aavarana is called "Pura." As it consists of 3 aavaranas it is called "Tripura" vimaana. It is operated by the motive power generated by solar rays.
Narayana also says:
The vimaana which naturally can travel on land, sea, and in the sky by alteration of its structure is called Tripura Vimaana.
It has got 3 parts. The first part can travel on land. The second part can travel under and over water. The 3rd part travels in the sky. By uniting the 3 parts by means of keelakas, the plane can be made to travel in the sky. The plane is divisible into 3 parts so that it might travel on land, sea, or air. The construction of the 1st part is now explained. Tripura vimaana should be made out of Trinetra metal only.
Trinetra loha is explained by Shaakataayana:
Jyotishmatee loha 10 parts, kaanta-mitra 8 parts, vajramukha loha 16 parts, these 3 to be filled in crucible, then adding tankana or borax 5 parts, trynika 7 parts, shrapanikaa 11 parts, maandalika 5 parts, ruchaka or natron 3 parts, mercury 3 parts, then filled in crucible in padmamukha furnace and heated to 631 degrees with trimukhee bellows, the resulting liquid, if poured into cooler, will yield a metal, shining like peacock feather, unburnable, unbreakable, weightless, impregnable by water, fire, air and heat, and indestructible.
